A multianalytical approach for the study of colored glaze decoration: the case study of Vieillard & Cie Manufactory (France, 19th century)

Résumé

During the second half of the 19th century, fabrication of ceramic pieces decorated with relief glazes occupied a prominent place in French factories of white earthenware. It is through the example of the production of the Vieillard and Cie Manufactory (Bordeaux, France, 19th century) that we will approach the technical study of this decoration process. The purpose of this paper is to better understand the production specificities of this decorative technique. A second part of the presentation concerns the development of optical techniques based on reflectance spectra and hyperspectral imaging. These non-invasive methods are intended to characterize colored glaze and more specifically, to identify the types of pigments used. A corpus of some fragments of glazed earthenware from archaeological excavations, that took place in the waste dumps of the Vieillard and Cie manufactory, has been studied here. Multianalytical methods were carried out in order to characterize both the clay support and the colored glazes. The methodology implemented consists in combining a thorough study of the sherds by destructive analyses with non-invasive techniques (SEM-EDS, Raman microspectrometry, LIBS, hyperspectral imaging). All the data obtained made it possible to better understand the nature of the decoration chromogens and thus, to establish the color palette of the artists who produced this type of decorative objects. Therefore, the aim is to build a database established on hyperspectral imaging, which will then be used when studying objects that must not be sampled. This work is a preliminary step towards the non-invasive study of objects from museums and private collections.
